[Help-bash] Command completion for an alias

[contact]

Hi folks!

My .bashrc defines some aliases like alias gs='git status'. I'd like to 
enable command completion for aliases so that when the command line is 
(| is the cursor):

$ gs |

and I press Tab I'd like to see the completions as if I typed 'git 
status '. I found a bunch of resources demonstrating how to do this 
[1][2][3] but in my opinion they lack elegance. My question is: how to 
make completion work for aliases? If bash needs to modified where should 
I start looking in the source code?

Best regards
